Yiddish Calendar - Tomsk (Siberia), 1919 - Two Rare Booklets, Bibliographically Unknown

Yiddish calendar, with synagogue customs, for the year 1919-1920, by "Pinchas Jeidel of Frankfurt am Main". Tomsk (Siberia), [1919]. Hebrew, Yiddish and Russian. Two variant copies.
Two copies of a calendar for 1919-1920 - one finished copy, and a second copy, not fully printed, partially completed by hand.
In the finished copy, the inside of the front cover contains information about the cycle of years and a section entitled "Jewish Chronic", containing a list of historic events in Jewish history. On the back cover of this copy, the title of the calendar was printed in Russian ("Jewish Calendar 1919-1920"), around a Star of David. Beneath the title, a logo with the inscription "Brauner Tom & Co." and the inscription "Printed by hand" (in Russian).
In the second copy, the inside of the cover remains blank, and in some leaves, the printing is incomplete - lacking the names of the Festivals, the Moladot, the prayer customs, and more. In three of the leaves which were printed in part only, the days of the
week and the dates were completed by hand.
Enclosed is a printed paper label, in Russian and German, which was used for sending packages to war prisoners in Siberia (Kriegsgefangenen-Sendung). The name of the POW - Siegfried Jeidel, is printed on the label (this may be the German name of the editor of this calendar, whose Jewish name was Pinchas Jeidel), with his address in the Dauria camp.
Two booklets. 12 pages + cover in each. 17.5 cm. Good-fair condition. Stains. Cover of one booklet detached.
The calendar is not listed in the Bibliography of the Hebrew Book, nor does it appear in the NLI catalog. To the best of our knowledge, it is not listed in any other bibliographic source.
We are not aware of any other Hebrew items printed in Tomsk, Siberia.
